Strawberry plant named &#39;bg-12.3258&#39;

ABSTRACT

This invention relates to a new and distinct variety of strawberry plant named ‘BG-12.3258’. This new strawberry plant named ‘BG-12.3258’ is primarily adapted to the growing conditions of the central coast of California, and is primarily characterized by its orange red to red fruit color, large fruit size, and conical fruit shape; very good fruit flavor, with seeds held even with the surface; medium plant size, semi-upright in habit, with medium vigor and density; medium yellow green foliage color, small foliage size, with three to four leaflets; fruiting trusses typically held beneath the foliage, with strong pubescence and very weak anthocyanins; and resistance to Fusarium wilt and moderate resistance to powdery mildew.

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority from U.S. Provisional Patent Application No. 63/250,523, dated Sep. 30, 2021. The contents of this application is incorporated herein by reference in its entirety.

Latin name of the genus and species of the plant claimed: Fragaria ananassa.

Variety denomination: ‘BG-12.3258’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct strawberry variety named ‘BG-12.3258’. This new variety is a result of a controlled cross made in 2012 in an ongoing breeding program between strawberry variety designated ‘BG-6.3024’ (U.S. Plant Pat. No. 25,895) as the seed (female) parent, and strawberry variety designated ‘BG-7.3065’ (not patented) as the pollen (male) parent. The variety is botanically known as Fragaria ananassa.

The seedling resulting from the aforementioned cross was selected from a controlled breeding plot in Ventura County, Calif. in the spring of 2014. After its selection, the new variety was asexually propagated by stolons in both Siskiyou County, Calif. and San Joaquin County, Calif. The new variety was extensively tested over the next several years in fruiting fields in Ventura County, Calif. This propagation has demonstrated that the combination of traits disclosed herein as characterizing the new variety are fixed and remain true-to-type through successive generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

‘BG-12.3258’ is primarily adapted to the climate and growing conditions of the central coast of California. The nearby Pacific Ocean provides the humidity and moderate temperatures needed to produce a strong, vigorous plant and maintain fruit quality during the winter and spring production months.

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘BG-12.3258’, which in combination distinguish this strawberry plant as a new and distinct variety:

-   -   1. Fruit ranges from orange red to red in color, large in size,         and conical in shape;     -   2. Fruit has very good flavor, with seeds held even with the         surface;     -   3. Plant is medium in size, semi-upright in habit, with medium         vigor and density;     -   4. Foliage is medium yellow green in color, small in size, with         three to four leaflets;     -   5. Fruiting trusses are typically held beneath the foliage, with         strong pubescence and very weak anthocyanins; and     -   6. Plant is resistant to Fusarium wilt and moderately resistant         to powdery mildew.

The strawberry variety that is believed to be most closely related to the new variety ‘BG-12.3258’ is ‘BG-6.3024’ (U.S. Plant Pat. No. 25,895). In side-by-side comparisons to the similar strawberry variety ‘BG-6.3024’, ‘BG-12.3258’ differs by the following combination of characteristics as described in Table 1.

TABLE 1 ‘BG-4.367’ Characteristic ‘BG-12.3258’ (US PP25, 865) Fruit: Color Ranges from Red orange red to red Fruit: Much longer Slightly longer L × W ratio than broad than broad Fruit: Firmness Medium to firm Firm to very firm of flesh Fruit: Flavor Very good Good to fair Fruiting truss: Short (21.3 cm) Medium (25.7 cm) Length Pedicel: Strong Weak to medium Texture (pubescence)

For identification, a series of molecular markers have been determined for this new variety.

‘BG-12.3258’ differs from its parents, ‘BG-6.3024’ and ‘BG-7.3065’ by the following combination of characteristics as described in Tables 2 and 3.

TABLE 2 ‘BG-6.3024’ Characteristic ‘BG-12.3258’ (US PP25, 895) Fruit: color Ranges from Red orange red to red Fruit: flavor Very good Excellent Plant: size Medium Ranges from medium tolarge Fruiting truss: Absent or Ranges from anthocyanin very weak weak to intensity medium Disease and Resistant Susceptible pest reactions: Fusarium wilt

DETAILED BOTANICAL DESCRIPTION

The new variety ‘BG-12.3258’ has not been observed under all possible environmental conditions. The characteristics of the new variety ‘BG-12.3258’ may vary in detail, depending upon variations in environmental factors, including weather (temperature, humidity and light intensity), day length, soil type and location. In addition, the characteristics of any parental variety or comparison variety included in Tables 1, 2 and 3 of the present invention may vary in detail, depending upon variations in environmental factors, including weather (temperature, humidity and light intensity), day length, soil type and location.

The aforementioned photographs, together with the following description of the new variety ‘BG-12.3258’, unless otherwise noted, are based on observations taken during the 2022 growing season in Ventura County, Calif. These measurements and ratings were taken from plants of ‘BG-12.3258’ dug from a high-elevation nursery located in Siskiyou County, Calif. during early October 2021 and planted approximately four to five days later in Ventura County, Calif. The approximate age of the observed plants is five to six months. Yield observations including average weight and marketable yield, along with fruit quality characteristics including soluble solids, are averaged from six years of data collected from the 2016 through 2021 growing seasons. Flower measurements and characteristics are from secondary flowers unless otherwise noted. Fruit characteristics and measurements are from secondary fruit, unless otherwise noted.

Where noted, color terminology follows The Royal Horticultural Society Colour Chart, London, Sixth Edition (2015).
